Trooper Steve Limani said a corporal tied the helicopter down and planned to refuel it when a wind gust upwards of 60 mph knocked it over at Arnold Palmer Regional Airport in Latrobe.

"They were going to fuel it first in case there's an emergency. The fueling process takes a little bit of time, so the general practice is, when you land the helicopter, the pilots will want to fuel it in case there's some type of emergency," said Limani.

Officials were still assessing the damage and how long the chopper will be out of service.

The helicopter belongs to troopers in Altoona and was being used by local troopers while theirs was being serviced and inspected.

No one was injured.
